Description

Technical Field

[0001] The present invention relates to the technical field of dialysis positioning, and specifically to a peritoneal dialysis positioning device for nephrology. Background Art

[0002] Peritoneal dialysis is one of the important means for the treatment of end-stage renal disease in nephrology. The traditional fixation methods of peritoneal dialysis catheters mainly rely on adhesive tapes or simple skin patches. These methods have many problems, especially in terms of skin comfort and breathability. The adhesive tape is prone to failure during long-term use, resulting in catheter displacement and increasing the risk of infection. In addition, the adhesive tape directly contacts the skin, which may cause skin allergies, redness, and tenderness.

[0003] After retrieval, the Chinese invention patent with the publication number CN113995904B discloses a peritoneal dialysis positioning device for nephrology clinical use. By setting an activity ring, a fixed ring, a moving ring rod, and a fixed ring rod, pulling the inner tube drives the moving ring rod and the fixed ring rod to change the angle, so as to realize their folding. Then, the fixed ring rod and the moving ring rod stretch the elastic soft film to form an umbrella-shaped surface for positioning on one side of the patient's peritoneum, so that the inner tube and the outer tube can be fixed more stably. By opening ventilation holes on the belt, the breathability and comfort during wearing are improved.

[0004] In related technologies, when the existing abdominal dialysis positioning device is in use, a belt structure is generally used to wear the positioning component on the patient's abdomen. However, although the belt method ensures the positioning of the abdominal dialysis tube, it ignores the problem of skin comfort during long-term wearing. The traditional treatment method is generally to use a fabric with good breathability or to open ventilation holes on the belt to improve its wearing comfort. However, when the belt is in close contact with the skin at the same position for a long time, the skin at this position cannot be relaxed for a long time, and it is still easy to cause skin allergies, redness, and tenderness. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a peritoneal dialysis positioning device for the department of nephrology.

The adjusting member can not only adjust the tightness of the two groups of several belts to meet the needs of different people, but also convert and adjust the tightness of the two groups of several belts. Through the conversion of the tightness of the two groups of several belts, not only the air permeability of the skin position is improved on the premise of ensuring the stability of abdominal dialysis positioning, but also it is convenient for the accompanying personnel to wipe the skin position, thereby improving the comfort of the patient's abdominal dialysis, and solving the problem that the wearing structure in the existing peritoneal dialysis positioning device is prone to cause skin allergies, redness, and tenderness when in close contact with the skin at the same position for a long time.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1:

[0042] Referring to the attached Figures 1-8 , a peritoneal dialysis positioning device for nephrology includes a transparent sealing cover 1 for positioning a dialysis tube. A belt assembly 2 is installed on the transparent sealing cover 1, and a detection component 3 for detecting the pulling of the dialysis tube is arranged on the front surface of the transparent sealing cover 1;

[0043] Through the setting of the transparent sealing cover 1, it is used to perform positioning and protection treatment on the position of abdominal intubation. Through the setting of the belt assembly 2, it is used to fix the transparent sealing cover 1 installed at the abdominal position, thereby improving its positioning and protection effect;

[0044] By setting the detection component 3, when the dialysis tube is positioned, when it is pulled, not only can the pulling force be buffered, but also an alarm can be issued immediately, so that the patient or the accompanying personnel can understand it in time;

[0045] The belt assembly 2 includes a plurality of first belts 21 and a second belt 22. One end of each of the first belts 21 and the second belt 22 is connected to one side of the transparent sealing cover 1 through an adjusting member 24.

[0046] The waistband assembly 2 is composed of a plurality of first waistbands 21 and second waistbands 22, which not only increases the contact range of the waistband when worn, increases the stability of the waistband when positioned, but also improves the air permeability when worn.

[0047] A plurality of first waistbands 21 and second waistbands 22 are arranged in a cross array;

[0048] The plurality of first waist belts 21 and second waist belts 22 are arranged in a cross array, so that when the tightness of the first waist belt 21 and the second waist belt 22 is switched and adjusted, the plurality of first waist belts 21 or the second waist belt 22 can independently ensure the stability of the positioning device when it is worn;

[0049] A connecting belt 23 is fixedly connected between the other ends of the plurality of first waistbands 21 and the second waistbands 22, and one end of the connecting belt 23 is connected to the other side of the transparent sealing cover 1;

[0050] A connecting belt 23 is fixedly connected between the other ends of the first belts 21 and the second belts 22, and the connecting belt 23 is connected to the other side of the transparent sealing cover, so that the belt assembly 2 forms a ring state, thereby facilitating the stability of the positioning device when being worn;

[0051] The adjusting member 24 is used to adjust the tightness of the first waist belts 21 and the second waist belts 22;

[0052] By setting the adjustment member 24, not only the tightness of the plurality of first waist belts 21 and the second waist belts 22 can be adjusted to meet the needs of different groups of people, but also the tightness of the plurality of first waist belts 21 and the second waist belts 22 can be switched and adjusted. By switching the tightness of the plurality of first waist belts 21 and the second waist belts 22, not only the ventilation effect of the skin position is improved while ensuring the stability of the abdominal dialysis positioning, but also the accompanying personnel can wipe the skin position conveniently, thereby improving the comfort of the patient's abdominal dialysis.

[0053] Refer to the attached Figure 2 , Figure 6 and Figure 7, a sealing sleeve 11 is fixedly connected to the front of the transparent sealing cover 1. A fixator 12 for positioning the dialysis tube inserted inside the sealing sleeve 11 is arranged on the front of the transparent sealing cover 1. An annular sealing layer 13 is installed on the back of the transparent sealing cover 1;

[0054] Through the setting of the sealing sleeve 11, it is used to ensure the sealing performance when the dialysis tube is inserted into the transparent sealing cover 1, thereby improving the subsequent adsorption effect of the transparent sealing cover 1;

[0055] Through the setting of the annular sealing layer 13, it is used to further improve the stability of the transparent sealing cover 1 when adsorbed on the abdomen;

[0056] The fixator 12 adopts a fixing structure in the prior art for clamping and fixing a hose, and is used to fasten the dialysis tube inserted on the transparent sealing cover 1 to ensure the stability during abdominal dialysis.

[0057] Refer to the appendix Figure 3 and Figure 4 , the adjusting member 24 includes a cylindrical tube 241 rotatably connected to one side of the transparent sealing cover 1 through a rotating frame. A plurality of winding discs 242 are rotatably connected inside the cylindrical tube 241, and a plurality of the first belts 21 and the second belts 22 are respectively wound on the outer surfaces of the plurality of winding discs 242;

[0058] By rotatably connecting a plurality of winding discs 242 inside the cylindrical tube 241, and respectively winding a plurality of the first belts 21 and the second belts 22 on the outer surfaces of the plurality of winding discs 242, it is convenient to drive the first belt 21 or the second belt 22 to adjust the tightness by rotating the winding discs 242, thereby improving the comfort during wearing;

[0059] It should be noted here that the rotation of the winding disc 242 can be driven manually or electrically.

[0060] Refer to the appendix Figure 4 , a rotating shaft 243 is rotatably connected inside the cylindrical tube 241. A plurality of winding discs 242 are all fixed on the outer surface of the rotating shaft 243. The top end of the rotating shaft 243 extends to the top of the cylindrical tube 241. The top end of the rotating shaft 243 is fixedly connected with a rotating handle. A fastening bolt 244 for locking the rotated rotating shaft 243 is threadedly installed on the top of the cylindrical tube 241;

[0061] A plurality of winding discs 242 are all fixed on the outer surface of the rotating shaft 243, so that by driving the rotation of the rotating shaft 243, a plurality of winding discs 242 can be synchronously driven to rotate, thereby forming the adjustment work of the tightness of the first belt 21 or the second belt 22. Through the setting of the fastening bolt 244, it is used to lock the rotated rotating shaft 243, thereby improving the stability after the tightness adjustment of the first belt 21 or the second belt 22;

[0062] A plurality of first belts 21 and second belts 22 are respectively wound around a plurality of winding discs 242 in opposite directions;

[0063] By winding a plurality of first belts 21 and second belts 22 around a plurality of winding discs 242 in opposite directions respectively, when the rotating shaft 243 rotates, not only can a plurality of first belts 21 be relaxed, but also a plurality of second belts 22 can be straightened synchronously;

[0064] Or when the rotating shaft 243 rotates, not only can a plurality of first belts 21 be straightened, but also a plurality of second belts 22 can be relaxed synchronously, forming the conversion of the tightness of a plurality of first belts 21 and second belts 22. Through the conversion of the tightness of a plurality of first belts 21 and second belts 22, not only can the air permeability effect of the skin position be improved on the premise of ensuring the stable positioning of abdominal dialysis, but also it is convenient for the accompanying personnel to wipe the skin position, thereby improving the comfort of the patient's abdominal dialysis.

[0065] Embodiment 2: Different from Embodiment 1;

[0066] Refer to the appendix Figure 6 and Figure 8 The detection component 3 includes a mounting seat 31 fixed on the front surface of the transparent sealing cover 1 and an alarm control box 34 fixed on the top of the transparent sealing cover 1. Two buffer members are arranged on the top of the mounting seat 31, and the two buffer members are connected by a connecting frame 32. A touch switch 33 is fixedly connected inside the mounting seat 31, and the touch end of the touch switch 33 contacts the bottom of the connecting frame 32;

[0067] Through the setting of the two buffer members, it is used to buffer the dialysis tube, so that the dialysis tube can be stretched within a small range, improving the adaptability of the dialysis tube, and solving the problem that in the prior art, after the positioning device clamps the dialysis tube, the dialysis tube cannot perform stretching movement, resulting in the dialysis tube being prone to overall movement when the dialysis tube is pulled later, and it is easy to change the position of the dialysis tube or cause the dialysis tube to break or the port to become loose;

[0068] Through the setting of the touch switch 33, it is used to control the alarm control box 34. When the dialysis tube is pulled, the two buffer members can buffer the pulling force. Cooperating with the movement of the connecting frame 32, the contact with the touch switch 33 can be lost. After receiving the instruction, the touch switch 33 performs an alarm process through the alarm control box 34, preventing the patient or the caregiver from failing to be aware of the pulling of the dialysis tube in a timely manner and taking corresponding protective measures;

[0069] The number of the fixators 12 is two. One of the fixators 12 is fixed to the front surface of the transparent sealing cover 1, and the other fixator 12 is connected to the two buffer members;

[0070] With two fixators 12, it not only improves the positioning and clamping effect of the dialysis tube, but also can trigger the alarm work through the other movably installed fixator 12; when installing the dialysis tube, the dialysis tube is threaded through the two fixators 12, and finally inserted into the abdomen through the position of the sealing sleeve 11 to perform abdominal dialysis work;

[0071] The length of the dialysis tube between the two fixators 12 is greater than or equal to the distance that the movably installed fixator 12 can move.

[0072] The buffer member includes a guide rod 35 fixed to the top of the mounting seat 31. A raised edge is provided at the top of the guide rod 35. A buffer block 36 is slidably sleeved on the outer surface of the guide rod 35, and the buffer block 36 is connected to the connecting frame 32. A first spring 37 for pressing the buffer block 36 downward is sleeved on the outer surface of the guide rod 35. A connecting rope 38 is fixedly connected to the top of the buffer block 36, and one end of the connecting rope 38 is fixedly connected to the other fixator 12. A guide hole for guiding the connecting rope 38 is provided on the raised edge;

[0073] The buffer block 36 is connected to the movably installed fixator 12 through the connecting rope 38. Thus, when the dialysis tube is pulled, the fixator 12 can perform a pulling movement. The buffer block 36 can be pulled through the connecting rope 38, and finally the touch switch 33 is turned on through the connecting frame 32 to form an automatic alarm work. Through the setting of the first spring 37, it is used to press the buffer block 36 downward, so that when the dialysis tube is not subjected to a pulling force, the dialysis tube between the two fixators 12 is in a contracted state, facilitating subsequent pulling buffering work.

[0074] Embodiment 3: Different from Embodiment 1;

[0075] Refer to the appendix Figure 5 , a negative pressure assembly 4 is provided on the other side of the transparent sealing cover 1, and the negative pressure assembly 4 is connected to the connecting belt 23. The negative pressure assembly 4 is used to adjust the internal pressure of the transparent sealing cover 1;

[0076] The negative pressure component 4 is provided to adjust the pressure inside the transparent sealing cover 1, thereby changing the stability of the transparent sealing cover 1 adsorbed on the abdomen and enhancing the positioning of peritoneal dialysis.

[0077] The negative pressure component 4 includes a negative pressure frame 41 fixed to the other side of the transparent sealing cover 1. An air extraction pipe 42 and a ventilation pipe 43 are arranged on the negative pressure frame 41. The air extraction pipe 42 is communicated with the inside of the transparent sealing cover 1, and a filter tip is installed at one end of the ventilation pipe 43.

[0078] The air extraction pipe 42 is provided to extract the gas inside the transparent sealing cover 1, thereby increasing the negative pressure intensity inside the transparent sealing cover 1 and improving the stability when the transparent sealing cover 1 is adsorbed on the abdomen.

[0079] A piston plate 44 is hermetically slidable inside the negative pressure frame 41. One side of the piston plate 44 is fixedly connected to a telescopic frame 45, and one side of the telescopic frame 45 extends to the outside of the negative pressure frame 41. One end of a connecting belt 23 is detachably connected to one side of the telescopic frame 45. A second spring 46 for elastically extruding the piston plate 44 is arranged inside the negative pressure frame 41.

[0080] The connecting belt 23 is connected to the piston plate 44 through the telescopic frame 45, so that when the belt assembly 2 is tightened, the piston plate 44 can be directly driven to be pulled, and then the gas inside the transparent sealing cover 1 can be extracted through the air extraction pipe 42, thereby improving the stability of the transparent sealing cover 1 adsorbed on the abdominal position and having the function of double-layer positioning and fixing. On the contrary, when the belt assembly 2 is relaxed, the adsorption strength of the transparent sealing cover 1 can be reduced.

[0081] Moreover, the installation positions of the air extraction pipe 42 and the ventilation pipe 43 can be set in reverse. So that when the belt assembly 2 is relaxed, the piston plate 44 is extruded by the second spring 46. When the piston plate 44 is subjected to the extrusion force, the gas inside the transparent sealing cover 1 can be extracted through the air extraction pipe 42, thereby avoiding the problem that when the patient moves, the belt assembly 2 is prone to loosen, resulting in the decline of peritoneal dialysis positioning performance. And through the setting of the second spring 46, a reaction force can also be applied to the belt assembly 2 through the telescopic frame 45, thereby avoiding the problem that the belt assembly 2 is overly loose, and having the function of wearing buffer and improving the wearing comfort.

[0082] The ventilation pipe 43 is provided to improve the smoothness of the telescopic movement of the piston plate 44.

[0083] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not expressly listed, or elements that are inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "including an..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0084] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
